FE_Interview

Purpose

• Initially this project is geared towards Front End Engineers preparing for a technical interview.

• It allows the user to simulate an online test with randomized questions and timer.

• Afterward the user can review the test and see a summary of the questions/topics which need to be reviewed further.

• This application does not provide correct answers or grading of the user's responses.

Credits

• The main content for this application was sourced from this project: https://github.com/h5bp/Front-end-Developer-Interview-Questions

Dependencies

• PosgreSQL should be installed locally (v10.5+). https://www.postgresql.org/

• Parcel is used to bundle and build the Front End files. It should be installed globally. http://npmjs.com/package/parcel-bundler

Database Setup

1 Create a database named fe_interview_db.

2 Create a database user with admin rights for the new database (read, create, update, delete). Record the user's password.

Setup (local/development)

Install files

1 Install root-level files.

yarn install

2 Install back-end files.

cd server && yarn install

3 Install front-end files.

cd ../client && yarn install

Server setup

1 Convert questions from markdown source files to JavaScript.

cd ../server && node test_md_to_json.js

2 Create the database (Postgres).

yarn run configure

3 Copy environment variables file in server root directory.

cp .env.example .env

• JWT_SECRET: to be used as a salt to encrypt strings used in authentication; this can be an arbitrary string, preferably complex

• DB_USER: the user name for fe_interview_db database

• DB_PASSWORD: the password for DB_USER

4 Update server environment variables (in .env file).

5 Seed the database.

node seed_db.js

Run the servers

1 Start the back-end server.

yarn run start

2 Start the front-end server.

cd ../client && yarn run start

3 From a browser, open http://localhost:1234

Automated Tests

Front-end

• Run from the /client directory

1 yarn run test

Using the Application

To create a random front-end interview test

1 Click New Test.

2 Name the test and select how many questions from each category to include.

3 At this time, it is expected that the user will take the test immediately after it is generated.

Deploy

• Notes in wiki for heroku deployment
